BACKGROUND OF THE INVENTION

Modern healthcare providers are learning that true healthcare involvesmuch more than perfunctory attention to physical ailments. The best careembraces the full spectrum of needs of a patient. A patient that iscomfortable with attention and treatment is indeed likely to benefitfrom participation in preventative practices and regularly scheduledappointments for care. Indeed, preventative medicine is thought to be akey to the future in lowering healthcare costs and in improving qualityof life.

A distraction from what may otherwise be an uncomfortable or awkwardprocedure can help a patient relax and can thereby reduce both physicaland mental stress and increase the tolerance of the patient during alengthy procedure. If improvement to the full experience of the patientcan be achieved, then the patient is more likely to pursue elective careservices. This may be of particular importance in, for example, the oralcare industry where dentists have suffered since the conception of theircraft against a reputation for providing needed but often uncomfortableservices to patients.

Even routine healthcare services such as oral hygiene procedures canprovide a less than optimal patient experience. Patients are typicallyat least bored while receiving such care. The overall experience of thepatient could be substantially improved by some convenient arrangementfor entertainment.

In addressing the need for patient distractions, many dentists nowincorporate into the provision of healthcare the presentation of audioand/or video content to patients while the patients are receivinghealthcare services. In this regard, computer monitors and televisions,headphones, and even virtual reality goggles are provided in order toprovide patient distraction from dental procedures. The monitors andtelevisions are incorporated into the dental treatment rooms bypositioning them into or on top of cabinets in the treatment rooms, ormounting them on arms attached to dental chairs. The view of thesemonitors and televisions provided to the patient, however, is less thanoptimal, as many dental procedures require the patient to be fullyreclined in the dental chair. Headphones also inhibit effectivecommunication between the patient and provider of the healthcare serviceduring the procedure. Virtual reality goggles may be similarlyobstructive and are not comfortable to some patients who experienceclaustrophobia.

Accordingly, a need continues to exist for improvements in the provisionof healthcare and, especially, dental health care. This, and otherneeds, are addressed by one or more aspects of the present invention.

As a preliminary matter, it will readily be understood by those personsskilled in the art that the present invention is susceptible of broadutility and application in view of the following detailed description ofpreferred embodiments. Furthermore, many embodiments as well asadaptations, variations, modifications, and equivalent arrangements,will be apparent from or reasonably suggested by the preferredembodiments described herein without departing from the scope of thepresent invention. Accordingly, while the present invention is describedherein in detail in relation to preferred embodiments, it is to beunderstood that this disclosure is illustrative and exemplary and ismade merely for purposes of providing a full and enabling disclosure ofthe present invention. The disclosure herein is not intended, nor is tobe construed, to limit the scope of the present invention, which isdefined by the claims and the equivalents thereof.

Turning now to FIG. 1, a preferred embodiment of an electronic displayassembly of the present invention is illustrated from an elevationalside view, and further is illustrated from a plan view in FIG. 2. Thispreferred embodiment includes a pivot arm 10, a swivel arm 12, and anelectronic display 14. The pivot arm 10 is coupled at a distal end 16thereof to a distal end 18 of the swivel arm 12. The coupling isaccomplished by a swivel 20 such that the pivot arm 10 can be variablyswiveled about a swivel axis 22 passing through the swivel 20.Similarly, the other distal end 24 of the pivot arm 10 is coupled to theelectronic display 14.

In this regard, a subassembly 26 couples the pivot arm 10 to theelectronic display 14, and includes a swivel 28 through which a swivelaxis 30 passes, a mounting member 32, and an elongate member 34extending between and connecting together the swivel 28 and the mountingmember 32. The elongate member 34 is pivotably mounted to the swivelmember 28 for pivoting movement about pivot axis 36. The elongate member34 also is pivotably mounted to the mounting member 32 for pivotingmovement about pivot axis 38. The elongate member 34 is rotatable aboutthe swivel axis 30 and includes two elongate side bars 40. The couplingof the elongate member 34 to the swivel 28 includes a post that extendsdownwardly from the swivel 28, to which both elongate bars 40 aredirectly secured by a first clamp bolt assembly and nut. Similarly, bothelongate bars 40 are directly secured to a post portion 42 of themounting member 32 by a second clamp bolt assembly and nut. The mountingmember 32 is removably attached via screws 44 directly to the electronicdisplay 14 in fixed relation thereto.

The pivot arm comprises a pair of parallel elongate members joined toform a four-bar-linkage parallelogram, and the pivot arm 10 is pivotableabout a pivot axis 46 and another pivot axis 48. The pivot axis 46passes through the distal end 16 of the pivot arm 10, and the pivot axis48 passes through the distal end 24 of the pivot arm 10. As will beappreciated by one having ordinary skill in the art, the design of thepivot arm 10 is such that raising or lowering of the electronic display14 by pivoting movement of the pivot arm 10 about both pivot axes 46,48permits the swivel axes 22,30 to remain in parallel relation.

The swivel arm 12 preferably is mounted to a ceiling of a room but,alternatively, may be mounted to a wall or other support. This mountingmay be accomplished by coupling the distal end 18 of the swivel arm 12to a carriage 50. This coupling is accomplished by a swivel 52 such thatthe swivel arm 12 can be variably swiveled about a swivel axis 54passing through the swivel 52, and a vertical member 57 that extendsbetween and connects this swivel 52 to the carriage 50. The verticalmember 57 is of sufficient mechanical strength to physically withstandthe tensile, shear, and torsional forces of supporting the electronicdisplay 14 and its coupling to the vertical member 57 in theirsuspension below the carriage 50. The swivel arm 12, in turn, includessufficient mechanical strength to physically withstand the tensile,shear, and torsional forces of supporting the electronic display 14 andits coupling to the swivel arm 12 in their suspension below the carriage50.

Each of the aforementioned swivels may include any suitable constructionand arrangement of bearings, races, cones, axles, or bushings to allowrotation.

As best shown in FIG. 3, the carriage 50 itself is secured to aceiling-mounted track 56 such that the carriage 50 can be variablypositioned along the overhead track 56 that extends generally parallelto the ceiling and that defines a translational axis. Translationalmovement of the carriage 50 along the overhead track 56 results insimple translational movement of, inter alia, the electronic display 14.The carriage 50 may be movably mounted to the track 56 by way ofbearings, rollers, glide bushings, collars and shafts, or any suitablemechanical coupling allowing the carriage 50 to be variably positionedalong the track 56.

As will be appreciated from the foregoing description, and as shown inFIG. 2, the swivel arm 12 is rotatable about the swivel axis 54, wherebythe swivel arm 12, the pivot arm 10, and the electronic display 14,together, are adjustably positionable about the swivel axis 54. Inaddition thereto, the swivel arm 12 is rotatable about swivel axis 22,whereby the pivot arm 10 and the electronic display, together, areadjustably positionable about the swivel axis 22 independent of theadjustable positioning of the swivel arm 12. The pivot arm 10 also ispivotable about the pivot axis 46 and the pivot axis 48, whereby thepivot arm 10 and the electronic display 14, together, are adjustablypositionable about the pivot axis 46 and pivot axis 48 independent ofthe adjustable positioning of the swivel arm 12.

Yet still, as shown in FIG. 1, the electronic display 14 is pivotableabout the pivot axis 36, whereby the electronic display 14 is adjustablypositionable about the pivot axis 36 independent of the adjustablepositionings of the pivot arm 10. The electronic display further ispivotable about pivot axis 38, whereby the electronic display is furtheradjustably pivotable about the pivot axis 38 independent of theadjustable positioning of the pivot arm 10. The electronic display 14also is rotatable about the swivel axis 30, whereby the electronicdisplay 14 is adjustably positionable about the swivel axis 30independent of the adjustable positionings of the pivot arm 10.

Notable characteristics of the illustrated embodiment in, for example,FIG. 2 include the fact that the swivel axes 54, 22, and 30 remainparallel to each other, and remain orthogonal to the translation axis58, throughout all of the aforementioned adjustable positionings.Similarly, each of the pivot axes 46 and 48 and pivot axes 36 and 38(FIG. 1) remain orthogonal to each of the swivel axes 54, 22, and 30throughout all of the adjustable positionings. In addition thereto, itwill further be noted that all of the pivot axes 46, 48, 36, and 38remain non-orthogonal to the translation axis 58 through a range ofadjustable positionings of the electronic display 14 and/or pivot arm10. In a preferred method, the electronic display assembly is utilizedto present audiovisual content to a person in a resting position.Accordingly, a preferred embodiment of an electronic display assembly isillustrated in FIG. 3 and includes the preferred embodiment of FIG. 1combined with an apparatus 60 for receiving a person in a restingposition. The apparatus broadly comprises, for example, a chair,recliner or bed and, in the field of providing a healthcare service, theapparatus preferably comprises a dental chair or operating table forsupporting a patient receiving healthcare.

As will become apparent from review of FIG. 3, the electronic display 14is suspended above, i.e., over, the apparatus 60 for convenient andunobstructed viewing by the person. Moreover, it thus will thus beappreciated that the electronic display 14 is coupled to a support suchthat the electronic display is adjustably positionable above theapparatus along each of three orthogonal axes, and such that theelectronic display is adjustably positionable along each of these threeaxes independent of adjustable positioning of the electronic displayalong the other axes, thereby insuring a convenient and unobstructedview thereof by the person. Furthermore, in embodiments wherein thetrack is mounted to a wall or other support other than a ceiling, theelectronic display 14 nevertheless preferably is still suspended abovethe apparatus 60 as shown in FIG. 3.

Aspects of the present invention include the presentation of audioand/or visual content to the person received in the apparatus 60. Asused herein, such content is intended to be of broad meaning. Visualcontent may include graphical images of any level of detail. Thegraphical images can appear fixed in time on the display or can bemoving or animated. The graphical images can be of live or recordedreal, imaginary, or virtual world scenes such as that found inentertainment programs and informative news programs. The graphicalimages can include a view of a healthcare procedure in real time, canpresent expected results of a procedure, or can display or alternatebetween views before and after completion of a procedure or proceduralstep. Visual content also may include visual sensory stimulations asused in seeing ability tests, optometric evaluations, healthcarepractices related to the eyes, psychological studies, or brain functionmapping techniques. Visual content may also include navigable menus andfolders such as implemented in conventional graphical user interfaces ofcomputing systems. Internet browsing can be available with the use ofthe electronic display. Word processing, accounting softwareapplications, and practice management proprietary or commercial softwareapplications can be utilized by a patient or healthcare provider usingthe electronic display. The visual content may also represent thefunctionally operative portions of a touchscreen.

Accordingly, FIG. 3 further serves to illustrate a preferred embodimentfor the wireless presentation of such content to the person whilereceived in the apparatus 60. In particular, a send unit 62 is operativefor wirelessly sending signals conveying content to be presented to theperson received in the apparatus 60. The send unit may comprise, forexample, a transmitter for broadcasting a wireless signal 64 to thereceive unit. The transmitter can be any suitable transmitter such as awireless router or RF transmitter, or an IR transmitter.

A receive unit comprising an antenna assembly 66 is disposed on theelectronic display 14 and is operative to receive the signals forpresenting of the visual content via the electronic display 14. Areceive unit comprising wireless headphones 68 having antenna 70 also isworn by the person and is operative to receive the signals forpresenting of the audio content via a speaker component of theheadphones 68. The audio content presented by the headphones 68 may beindependent of the visual content presented by the electronic display14, or the audio content presented by the headphones 68 may accompanyand be synchronized with the visual content presented by the electronicdisplay 14, as desired. In variations of such embodiments, theelectronic display 14 may include speakers and the antenna assembly 66may receive signals for both audio content and visual content. In suchvariations, the electronic display 14 may include a speaker componentfor presenting the audio content to the person, or the electronicdisplay 14 may include an output port such as a headphone jack forfurther communicating signals representing the audio content. In othervariations, a speaker component may be embedded in the headrest 72 ofthe apparatus 60 for presenting of the audio content. A preferredembodiment of an electronic display 69 incorporating a speaker componentcomprising speakers 71 therein is illustrated in FIG. 15. Moreover, thispreferred embodiment further includes handles 73 disposed on oppositesides of the electronic display 69 in order to facilitate the adjustablepositioning by the viewer.

The send unit 62 is shown in FIG. 3 as being attached to a wall;however, the send unit 62 may be disposed anywhere so long as thereceive units 66,68 are within its transmission range. Alternativelocations include being secured to the support to which the track 50 ismounted.

The send unit further may be disposed in electronic communication withsaid receive unit by a cable or wire connection of any suitable type forcarrying signals from the send unit to the receive unit. In embodimentsof the system that include such a connection, the connection ispreferably constructed, arranged, and routed to connect the send andreceive units through a pathway internal to the overhead structure thatsupports the receive unit. Such an arrangement and routing provides foraesthetic elegance in the environment of the system and, particularly ina healthcare environment, avoids cluttering of a patient care area. Thiswell complements a variable support assembly by allowing freedom ofmovement of a display without dangling wires congesting the immediatearea of a healthcare provider and patient. This variation is illustratedin FIG. 4, where cable 74 is shown extending between, and connecting inelectronic communication, both the send unit 76 with a receive unit inthe form of an input jack (not shown) of the electronic display 14, andthe send unit 76 with a receive unit in the form of an amplifierembedded in the apparatus 60 and having input and output jacks 78. Withadditional regard to this variation, the cable leading to the electronicdisplay 14 preferably is disposed internal to at least the swivels 52,20, and 28, whereby the cable does not inhibit the range of motion thatthe electronic display 14 otherwise enjoys.

With regard to another variation of the invention, the range of rotationof each swivel is limited, for example limited to less than fullrotation, in order to avoid twisting of a cable internal thereto. Such avariation comprises a bearing projecting from a detent under the forceof a spring to lock and arrest rotation at an extreme of an allowedrange.

The send unit 76 includes multiple inputs and is capable of receivingcontent from a range of disparate or related sources and sending signalsfor the various content to the receive unit in a unitary fashion. Therange of sources, within the scope of the invention here described,includes without limitation, any electronic accessory or interface thatproduces or relays signals that convey visual and/or audio content,including, but is not limited to: a video cassette recorder (VCR) orplayer; a digital video disk (DVD) recorder or player; a computer; acomputerized network, router, or interface; a television signal receiveror tuner; a cable signal receiver or tuner; a satellite signal receiveror tuner; a video camera; and digital X ray equipment. Thus, somemultiple inputs of the send unit 76 may include, for example, an S-videoinput, a cable input, a USB input, and an RCA input. The exemplaryembodiment 80 of the send unit illustrated in FIG. 5 includes a patchpanel with ports for VGA fifteen-pin, RCA (left audio, right audio, andvideo), S-video, USB, and commercial cable inputs.
